The larvae of Cryptocephalus and of the sub-genus Clythra, are thick and 

 curved at the posterior extremity like those of the Cockchafer ; they live 

 in cases, which they draw along with them, and which, according to GENIS, 

 are formed of their excrement. Ann. des Sc. natur. XX. 1830, p. 143.

Phalanx II. Galerucina (Galerucidce STEPH.). Antennae ap- 

 proximate at the base, inserted between the eyes near the mouth 

 (filiform, scarcely or not at all incrassated towards the apex, often 

 longer than half the body). 



Haltica ILLIG. (Altica GEOFFR.). Posterior feet saltatory, with 

 thighs incrassated.

 Tab. i, RATZEBURG, Forst-Ins. i. Tab. xx. fig. 8 ; 2'" long, bluish-green,

 As larva and perfect insect this little beetle eats all kinds of leaves of 

 trees, garden-plants and pot-herbs, and may cause great damage if it 

 multiplies largely. It is known by the name of earth-flea, under which 

 however other species are also included.
